TO ALL WHOM IT MAY CONCERN:

Be it known that I, CONRAD GEORGE, of Ligonier, Westmoreland county, and State of Pennsylvania, have invented a new and useful improvement in Churns; Yand I do hereby declare that the followingis a full, clear and exact description thereof, reference being had to the accompanying drawings, and the letters of reference markedtliereon, in which- Figure 1 is a perspective view ofthe entire churn, the sides being partly broken away to show the interior arrangement of the parts. I

Figure 2 is a plan view.

Figure 3 is a side elevationl of one of the dashers.

Figure 4 is a front elevation of the same.

Figure 5 is a longitudinal elevation of the parttion; and

Figure 6 is a section of thc same, taken on the line :v x of iig. 5.

Like letters refer to like parts in allthe gures.

To enable others skilled in theart to make and use my invention, I will proceed to describe its construction and operation. v i l A is the churn-box, in which the slattod and perforated partition B is placed, which partition slides in vertical grooves cut into the front and back sides of the box, (as indicated iii-dotted outline at r s', in iig. 2,) so as to be removable. X X are the lids, resting in grooves on the top of the box A. C is the frame, in which the churn-box A is placed. D D are standards, rmly attached to the frame C, and stiii'ened by braces E E. lThese standards are provided with slots at their upper ends, to receive the cross-bar F, which is retained firmly in its place by means of removable pins c c." Fastened to the cross-bar F are standards G H I, which form supports and fulcra for levers, now to bedescribed.` The working-lever J has its fulcrum at al, in the standard H. The secondary levers K L are attached to the standards G I by the fulcrum-screws ef. lo these levers are fastened the dasher-rods M N, by means of movable pins g L. The partition B is provided, at the bottom, with holes b b', and slits c c at the top, which slits are bevelled from both sides, as shown in figs. 5 and 6. The milk is chnrned by being forced through the holes in both the partition and the dasher-valves by the reciproeating motion of the dashers` This reciprocating motion causes it to flow back and forth through the slits, which collect the particles of butter, as fast as they are formed, in two' rolls, one' on each side ot' the partition.

The operation of the churn is as follows: Motion being given to the lever J, it is transmitted to the levers K L, by means of the screws or pins j working in slots k Z, (the levers K L being of the thirdv order.) This arrangement of levers not only gives an alternating motion to the dashers, but increases their throw, without increasing their distance apart-a very important circumstance, as upon it depends much of the compactness, convenience, and efficiency ofthe churn. The lower ends of the rods M N are constructed with broad bearing i plates m m, into which are let the transverse bearing-strips O O and P P, between which are hungperforated dasher-valves R R and S S, which vibrate on the pivots y y and z e. The strips O O and l? l? are provided with ledges, q q and r r, formed so as to prevent the valves R R and S S from opening upward beyond a horizontal position, as shown in red outline in fig. 3', the" normal position of the valves being shown in black in the same gure. As the dashers work up and down alternately, the valves R R and S S, in the descending dasher, p

i are forced up by the action of the milk to a horizontal position,l (as shown in the said ligure in red,) the milk being, at the same time, forced through the perforations in the dasher-valvcs RB and 4S S, and through 'the perforated bottom of the partition B. When the dasher has completed its downward stroke, and is rising, these valves are forced back to their former position by the weight of the superiucumbcnt milk and their own gravity.' Thus the dasher--valvcs rise and fall alternately, as the dashers are forced up and dorm in the act of churningn The object of the slitted rack or comb, iu the upper portion ofthe separating board or partition B, is to collect the butter as fast as it is formed. The particles floating upon the surface of the milk, and flowing back and forth alternately through these beveiled slit-S, are gathered and collected on each side of the slats' in two rolls or masses, which, when the churnino" is completed, are removed with great'ease, leaving no small particles remaining in the mi k, as is usual in other chorus, but collecting it all together, even to the smallest particles- In taking this churn apart to clean it, after use, take off the lid/S'X X, take .out the pins C C, and lift 01T the system of levers, with the flasher-rods and dashers attached. The dnsliers are t'hen removed from the levers, and. all the parts :ire in convenient form for -cleaning` and drying-4r very essential matter in all dairy utensils.

Having thus described the construction und operation ,of my invention, what I claim, ond desire'to secure by Letters Patent, is

v 1. I claim the combination of the double .alternating levers'J K L, and the partitioned churn-'box A, all arranged substantially as und for the purpose set forth.

2. I claim arranging the levers J K in o. diagonal position, as shown, for the purpose of brin-ing the working ends of the levers K L over the centres ofthe churn divisions A A', ns and for the purpose set forth.

3. I claim the combination of' the perforated dashers, provided with the valves R R :1nd S S, having the movements described, with the partition B, furnished with the holes Il b', and bevellcd slits c e', substantially :Ls and for the purpose set forth.

CONRAD GEORGE.
